Islam1, A.H.M. Kohinoor2, M.M. Rahman3*, M.M. Haque4 Received 30 April 2017, Revised 4 June 2017, Accepted 26 June 2017, Published online 30 June 2017 Abstract The study was carried out in IAPP commanding areas from July to September 2015. A total of 8 hatchery and 240 farmers were selected for this study from Rangpur and Barisal region. About 153% Tilapia production increased which was from 34 to 86 lakh, which was 148% in Rangpur district. Thai koi production was increased about 320% in Rangpur and it was 152% in Barisal. It was observed that, per hatchery Tilapia profit was Tk. 17.35 lakh and Tk. 17.18 lakh in Rangpur and Barisal, respectively. While, total profit was 3.9 times more for Thai koi in Rangpur and it was about 1.7 times more in Barisal after IAPP-BFRI project implementation. Impact of improved germplasm on grow out system was estimated. Finding shows that before IAPP-BFRI project the average harvesting weight of tilapia fish was 122g but after using IAPP-BFRI germplasm, it increased to 194g in Rangpur district. In case of Thai Koi, the harvesting weight gain was 26% in Rangpur district and it was statistically significant at 1% level. Survey results also show that per acre profit was only Tk.86671 for Tilapia farming before IAPP whereas it was increased to Tk. 234853 after IAPP-BFRI intervention. At the same time, profit from Thai Koi was increased about 189% after IAPP- BFRI activities. Similarly, profit was increased about 86% in case of Pangus farming and this positive impact was statistically significant at 1% level. Therefore, it may conclude that, farmers can significantly increase Tilapia, Thai Koi and Pangus production as well as can maximize profit using IAPP technology.

Rahman) Introduction Bangladesh is endowed with unique aquatic hectare yield from ponds only 3.0 tones per year. resources for fish and fisheries development. The This can further be augmented. The yield of inland water resources of this country are inland fisheries is therefore could be increased considered to be one of the richest in the world substantially through adopting appropriate both in terms of area and its potential for aquaculture technologies and judicious as well as fisheries development. Fisheries sector is efficient uses of existing resources. However, contributing in food security through proving safe sustainable aquaculture technologies as well as and quality animal protein; almost 60% animal quality fish fry are required in this country for protein comes from fish. It contributes 3.69% to increasing production of fisheries. our national GDP and around one fourth (23.12%) to the agricultural GDP (FRSS, 2016). It Integrated Agricultural Productivity Project provides full time employment to about 1.20 (IAPP) is donor funded project. This project is million people and generates part time implemented by Ministry of Agriculture and employment for 11 million people. Around 10% of Ministry of Fisheries and Livestock, Bangladesh. total export earnings come from fisheries. It was Under this project eight agencies (DAE, DLS, argued that rural aquaculture plays a significant DOF, BADC, BARI, BRRI, BFRI and SCA) are role in Bangladesh in view of its contribution working together to promote productivity of towards national food and nutritional security, crops, livestock and fish. During 2011-16, with the rural job opportunities and income (Mazid and financial assistance GAFSP, BFRI has been Sinha, 2000). Rural aquaculture thus needs much working for developing improved generation of more attention now than ever before. Although GIF tilapia, Thai Koi and Pangus. During the Bangladesh is rich in vast water resources but per timeframe, BFRI have successfully developed 04 58 Islam et al.

These improved generations with the objectives of the study. In this study, the were distributed to eight selected private tabular technique of analysis was used. The hatcheries of Rangpur and Barisal region for tabular technique of analysis included mass seed production. These selected hatcheries classification of the data in the form of tables. It is are being produced millions of quality fry from generally used to find out the crude association of BFRI supplied improved generation and sold out difference between two sets of variables. This among IAPP fisheries group member. The IAPP technique is based on arithmetic mean, group members were growing table sized fish for percentage, ratio, etc. economic welfare. The present study was Results undertaken to analyze the potential impact of quality fry production in hatcheries and culturing Table 1 shows the average fry production and its the improved generations on fish production and profitability status in Rangpur and Barisal profitability of fish farming. district. Fry of Tilapia production has reached to about 87 lakh per hatchery per year after IAPP Materials and Methods implementation, which was only 35 lakh before the project implying that Tilapia fry production The investigation was carried out in IAPP areas has increased about 148% in Rangpur district. from July to September 2015. Integrated Same success was observed in Barisal. About Agricultural Productivity Project (IAPP) worked 153% Tilapia production has increased which is in 54 upazillas in Rangpur, Kurigram, from 34 lakh to 86 lakh. On the other hand, a Lalmonirhat, Nilphamari, Barisal, Jalokathi, significant change has occurred in case of Thai Patuakhali and Borguna. The survey schedule was koi in Rangpur district. Thai koi production has prepared to record the required information on increased about 320% in Rangpur and it was various aspects of fish farming activities. A total 152% in Barisal. Cost of production has increased of 8 hatchery and 240 farmers were selected from with fry production but profitability has increased Rangpur and Barisal region for this study. After significantly for both places and species. It is the schedule was finalized, the selected farmers found that per hatchery Tilapia profit was Tk. were interviewed individually by personal 17.35 lakh and Tk. 17.18 lakh in Rangpur and interviews when they had little work on the Barisal, respectively. On the other hand, total farms. Before the actual interview was made, the profit was 3.9 times more for Thai koi in Rangpur aim and purpose of the study were explained to and it was about 1.7 times more in Barisal after each hatchery operator and farmers. IAPP implementation. Therefore, it can be concluded that, a significant success has achieved in case of fry production and profit in hatchery. Table 1. Average fry production status.
